1* Device tree bindings for Texas instruments Keystone timer 2 3This document provides bindings for the 64-bit timer in the KeyStone 4architecture devices. The timer can be configured as a general-purpose 64-bit 5timer, dual general-purpose 32-bit timers. When configured as dual 32-bit 6timers, each half can operate in conjunction (chain mode) or independently 7(unchained mode) of each other. 8 9It is global timer is a free running up-counter and can generate interrupt 10when the counter reaches preset counter values. 11 12Documentation: 13http://www.ti.com/lit/ug/sprugv5a/sprugv5a.pdf 14 15Required properties: 16 17- compatible : should be "ti,keystone-timer". 18- reg : specifies base physical address and count of the registers. 19- interrupts : interrupt generated by the timer. 20- clocks : the clock feeding the timer clock. 21 22Example: 23 24timer@22f0000 { 25 compatible = "ti,keystone-timer"; 26 reg = <0x022f0000 0x80>; 27 interrupts = <GIC_SPI 110 IRQ_TYPE_EDGE_RISING>; 28 clocks = <&clktimer15>; 29}; 30
